HONOLULU -- Hawaiian Airlines says it is the first airline to receive verified carbon credits for reducing emissions.
The airline announced Monday it has reduced its carbon dioxide emissions by nearly 22,000 metric tons over the past six years by using environmentally friendly engine washing technology.
A carbon credit is a way to measure the reduction of industrial carbon dioxide emissions. One credit equals removing one ton of carbon dioxide. The airline says its credits have been certified by a leading independent standard for measuring and verifying greenhouse gas emissions and the creation of carbon credits.
The airline says its engine washing system has had the equivalent of taking 700 cars off the road annually.
